Wow, that's a whole lot of gearing change. Make sure to keep an eye on the motor temps. Unless you were severely overgeared, you might have it geared to low now, lol.

I was geared 66 spur/40t pinion...i went to 76/30.... :gasp:

I looked up some info on the capacitors, and it said to solder them between the 2 power wires....there was a place for the pic, but it had been long since removed.

do those novak capacitors get soldered between the 2 wires from the esc that plug into the battery?

can i solder them to the wire and not the board?

solder them parallel (along with) the batt wires that go to the esc. The capacitor acts like a super fast charge/discharge battery, just put it as close to the esc as you can. Yes, the standard is to solder them to the esc wires, not the board.

thanks....i heard of someone in another forum using 3 of the capacitors...is there any advantage to this or will one be enough?

one is apearently enough, however the more the better if you have room/weight to spare ect... when you get multiple caps on there you do tend to wear the connectors fast (arc's). I did a 4 pack on mine, grouped them togeather and put a deans on the input and output. I used them on my XXXT but I don't on my 1/10th 4wd buggy...

you may be thinking of the upgrade to the existing 3 caps too. sorry, just clicked :)

thanks...much appreciated...

as to the 3 upgrade caps, i think i've seen that before somewhere.....i'm terrified to try to go solder anything to the boards...i think i'll try the novaks between the 2 power wires.

76/30 sounds more like it. 66/40 is crazy!

apparently the other 2 mambas thought so too. :lol:

I have VXL Rustler that I have a MM, 4 cell 5000 lipo, and 54/15 gearing, running the CC BEC and the Battery and ESC barely gets warm, and the Feigao 9L gets between warm and hot, and I dont run a fan or extra caps...I would shoot for about a 3.5-1 gear ratio and with the 4 cell and stock VXL motor your getting over 50,000 rpms I would say that is beyond its max

Well, i gotta hand it to you guys...when you're right... you're right... :yes::party:

I just came in from some testing, and temps never got above 117 degrees....and it's almost 75 outside right now....i lowered the timing and changed the gearing and gave it some punch control.

That was geared 76/30=2.53...i think i could go even a few teeth higher and it be fine....i might mess with the throttle curve too although i kinda like where it's at right now.

Crazy how sensitive this esc is compared to the vxl....with the vxl i could run 19 - 40t on the pinion and 7-10t difference on the spur and there be maybe 30 degree difference in temps.


With the mamba, 10 teeth on the pinion, 10 on the spur, and timing on high means thermal....just sucks that i had to go through 2 esc's before i got my head outta ...wait...huh? LOL ......and just asked for some help. CASTLE RULES!!!!

Again, thanks guys. :party:
